The correct names for the given complex ions are to be given. Concept Introduction: While naming complex ions, certain rules are to be followed, which may be summarised as follows: Ligands are named first as per the alphabetical order, followed by the metal atom. The cation is named before the anion, regardless of whether the complex has a net negative or positive charge. The name of an anionic ligand ends with the letter “o,” a neutral ligand’s name usually ends by the name of the molecule, except for H 2 O, CO, and NH 3 , which are named as aqua, carbonyl, and ammine, respectively. If the complex is an anion, the central metal atom ends in “-ate.” If two or more identical ligands are present, Greek prefixes, d i , t r i , t e t r a , and p e n t a , etc., are used. The oxidation number of the metal is expressed in Roman numerals, such as I, II, and III within the parentheses at the end of the name of the metal without any space between the name and the numeral.

While naming complex ions, certain rules are to be followed, which may be summarised as follows:

Ligands are named first as per the alphabetical order, followed by the metal atom.

The cation is named before the anion, regardless of whether the complex has a net negative or positive charge.

The name of an anionic ligand ends with the letter “o,” a neutral ligand’s name usually ends by the name of the molecule, except for H2O, CO, and NH3, which are named as aqua, carbonyl, and ammine, respectively. If the complex is an anion, the central metal atom ends in “-ate.”

If two or more identical ligands are present, Greek prefixes, di, tri, tetra, and penta, etc., are used. The oxidation number of the metal is expressed in Roman numerals, such as I, II, and III within the parentheses at the end of the name of the metal without any space between the name and the numeral.
